Stainless steel split pins are often used for securing threads such as turnbuckles or rigging screws and trailer wheel bearing nuts. Use our split pin size selection chart (in accordance with the standard DIN 94) to make sure your choose the right split pin for the job. Split pins are sometimes know as split cotter pins, and have a number of uses in and around the boat including the securing of threaded joints such as turnbuckles or rigging screws, and securing pivot pins such as cotter pins used in sailing pulley blocks. The stainless steel split pin is pushed through the securing hole (after the joint has been set or tightened to the right level) and then the legs of the split pin are bent outwards to keep it in place. When using split pins in areas near sails, such as in turnbuckles, or where people may go past please beware of the ends of the split pin which can cause damage. In these places it may be preferable to use marine grade ring pins instead. This means that the diameter of the new split pin is significantly smaller than its hole to allow it to be pulled out, even after the bent ends of the split pin have been straightened out with the aid of a screwdriver and pliers, they are never quite straight and the under-size of the split pin compared to the hole allows for an easier removal than if the split pin were a more exact match for the hole. ## Features - A4 316 MARINE GRADE STAINLESS STEEL – CORROSION RESISTANT IN SALTWATER & OUTDOOR USE Manufactured from A4 316 stainless steel — the premium marine-grade alloy containing molybdenum for superior resistance to saltwater corrosion, rust, and pitting compared to standard 304 grade. Suitable for permanent installations on boats, yachts, trailers, agricultural equipment, and coastal applications where lesser materials would corrode and fail within months. - DIN 94 STANDARD – PRECISION FIT FOR SHACKLES, CLEVIS PINS & RIGGING Precision-manufactured to the DIN 94 international standard for consistent dimensions and reliable fit in standard hole sizes. Designed for use with bow shackles, D-shackles, clevis pins, rigging hardware, and any drilled-hole locking application. The two legs spread apart after insertion to lock the pin in place — preventing accidental removal under vibration, load, or sudden impact. - 2.5 x 32mm – PACK OF 20 STAINLESS STEEL SPLIT COTTER PINS Each pack contains 20 individual 2.5mm x 32mm split cotter pins. The 2.5mm shank diameter fits drilled holes of 2.5mm nominal size, and the 32mm length suits applications where this protrusion provides enough material to bend the legs apart for secure locking. Ideal for marine rigging, trailer hardware, automotive, agricultural machinery, and engineering use. - SECURE LOCKING – PREVENTS ACCIDENTAL SHACKLE OR PIN RELEASE Once inserted through the drilled hole, the two legs of the cotter pin are bent apart with pliers to lock the assembly firmly in place. This simple, proven mechanism prevents shackles from opening, clevis pins from sliding out, and retaining bolts from disengaging under vibration or load. Removed easily when needed by straightening and withdrawing — perfect for serviceable connections. - VERSATILE – MARINE, TRAILER, AUTOMOTIVE, AGRICULTURAL & ENGINEERING USE Genuinely multi-purpose: covers boat shackle locking, yacht rigging hardware, trailer hitch and tow ball pins, caravan accessories, agricultural machinery retaining pins, automotive chassis fixings, motorcycle brake and suspension pins, ride-on mower deck attachments, and general engineering use.
